To all'wlwm it may concern:

Be .it known that I, Lnwls F. BnowN, a citizen of the United States,residin at Hammond, in the county of Roch and tate of Nebraska, haveinvented certain new and -useul Improvements in Loading Apparatus ofwhich the following is a specification.

'his .invention relates to loading a paratus and more particularly to aloa erdesigned for use in loading manure 4or dirt from the ground levelinto a wagon or other vehicle'in which it is to be conveyed.

It is one aim of .the present invention to so construct the loader thatthe dumping latform thereof will be' automatically dumped when it hasbeen elevated to the proper distance -above the ground surface and willbe automatically returned to receiving' or horizontal position in itslower.- ing movement.

Another aim of the invention, is to provide novel means for steadyingthe dumping platform as the same is elevated and lowered and .for firmlysupportingyflie platform in its movement from horizontal to dumpingposition so that the load carried thereby w1 l be directed withcertainty7 into the -wa on box which is to receive it and there wil beno likelihood oi-4 scattering of the material comprising the load .V

Fig. G'is' a view similar to Fig. 5-v illustrating ,the platform'indumped position.

They apparatus',l includes a supporting frame structure which may be ofany suitable construction but is here shown `as cemprising a base'v 1upon which .are mounted u rights 2. the uprights being-braced by in- Vc'ned brace'members `3 'secured at their upper.I ends. to .the uprightsand yat their lower ends to the said. base 1. The numeral 4. indicates.in general the receiving or load.,

ing platform ofthe structure and this plat form is suppor ',ed uponsills 5 and is' linclined downward] in avdirection away from theuprights 2. Side sills 6 are arranged an'd supported at their ends u onthe sills 5. Other braces 7 are secure at their upper ends tothe ulights 2 .and at their lower 4'ends to the sil s 6. At their upper endsthe upri hts 2 are 1 :onnected by cross beams 8 whic complete the framestructure.

The dumping form proper 1n :heated b v the numeral 9 and provided vithside boards 10 and a front board 11 Said platform rior to .loadingthereof is positioned as siown in Figs.' 1 and 2, u gon the base 1 andbetween the lower ends of the uprights` 2 with its front board- .1 1extending'close to and living against the real edge of the loading platform 4. The'ineans providedfoi raising and lowerin tl'e dumping platform9 includes a win ing; shaft 12 which is mounted in suitable bearings 13supported upon the crossbeams 8 at the upperends of the upriglits 2 andan intermediate bearing 1l sup'- latform comprises a plat.

eo f i ported upon the said beams 8 between their ends. Chains areconnected in any suitable manner to t. 1e shaft 12 at opposite sides ofthe bearing 1l and are led ldownwardly land connected ly means of branchchains 16 to the dumping platform 9'at the ends of the latter, tho pointof connection being" such that when the shaft 12 is rotated so as towind lthe. Vchains 15 thereon, theplatform 9 will be substantiallyevenlybalanced 4and will retain its lorizontal position as it isA raised andlower ed. In order that the shaft 12 may be rota :ed. a drum 17 issecured.` upon the-said sli aft at one end thereof andl wound upon thisdrum 17 is a cable 18 which" is led downwardly from the drum --andthrough a block 19 connected to thebasel.

The lcable is'prc vided atits end with anyl suitable form of hook orclevis 20 in order that a draft animal may be connected with theV cablefor the purpose of unwinding' the same from the di um 17 and therebyiinart-f` ing rotary motion to the shaft 12.

suspension members `'tilting Ato assume positions in a plane passing'through "the windshaft and the pins-*2'7.-'11`he platform will,consequently, be tilted to such Vanl extent vthat its contents will'bedumped and will be deposited in the spreader or other vehicle providedto receive 1t; -It\-may sometimes happen that the shifting-of the load'-ivill be accompaniedby a slackening of the that the platform anddownwardly.

tension in the cablelS so tends to .swing forwardly This movementcarries the pins 27 into engagement with thehook members 26 so that thedownward' movement of the rear side of the'y platform will be arrestedand if the Ywill -be held stationary and pawl, presently described, beshifted into engagementwith the pulley 17, so as to hold the saineagainst rotation, the winding shaft the platform will besupported intilted position by the pawl,

the' suspension means, the pins 27 and the hoo'ks 26 so that allparticles of the load which may tend to adhere to the platform maybescraped therefrom as'will be readily understood. If this' slight tion',during-the dumping operation, d oes not occur, the' tension of thesuspension members willvhold the pins 27 against the- -abutments 23 andthe hook members 26.

After the'entire'load has been discharged,

- the-platform will, of course, be lowered to receive another load andthe initial lowering movement will carry the pins 27 into enand aresecured to the.

.members so that the platiogm lnay Athen be [Referring now particularly-to Figs. 5 and 6 of the -draw1ngs, it will be observed one side of the'said 'winding d rum '17,

dropping operaf gagement with the bills of the hook members 2G so thatthe pins will rest in said hooks. The continued unwinding of thesuspension means will then causethe platform to swing toward ahorizontal position with the pins 27 as a center, thereby bringing thepins 21 against the frame vand the impact v'of the pins 21 against theframe will cause the pins 27' to ride out of the hook lowered while in ahorizontal position. As 7,5 shown clearly in Fig. 5, the distancebetween the pins 21 and 27 is greater than the horizontal distancebetween the uprights and the hook members. Then the move? A 8` ment ofthe tlltedv platform toward a hor1" o' vZontal position brings. the pins21 against.

the frame, the greater weight of the platform is exerted through thepins 21and the impact of the pins against the frame issufiicient tocau-se the pins 27ste ride. u p and out of the hook members. It'will benoted 'that thel bill or extremity7 ofthe hook member. is not parallelwith the shank 'of the same so that the pin V27' may be readilydislodged 90 therefrom althoughit will seat therein and will -aid inlsupporting the platform ifun-`lv disturbed. L The pawl and ratchetmechanism, above referred to, includes a bar 2S 'which is' piv- 95 otedat its lower end, as atl 29, upon one of the side sills -6 and extendsupwardly through a guide yoke 30 'secured upon the adjacent brace 7.This bar isprovided-'at f its upper end with A plate 31 secured inanysuitable manner to bar '28 and )rovided witha shoulder 3 2 and a curvedAnger 3 Normally the pawl rests by 'gravity-'in t e path of movement ofpins 3l arranged inan -105 annular series upon one side or end of lthethese .p ins servin01.t1le. same purpose as the teeth of'a ratchetbllhelinger serves by reason of engagement wlth the pin 3l, to limitthe.movement lof 110 I the bar 28 in the direction'of the said teethv andthe shoulder 32 serves as an abutment against. which the pins may'engage for the purpose of pre-venting backward rotation of the drum whenthe dumping platform has been elevated to the desired point. In orderthat the bar-28 may be held out of position,

coperation with the ,ratchet pins 34 upon the winding drum a. detentblock 35 is disposed ,against the 28 and is supported by one a1m36 of anangle lever, lthe other arnr37 of which constif' tutes a' handle throughthe medium of which the 4lever inay be rocked to move`thel block d .V 35upwardly or downwardly against'. the 125 rear side ofthe bar 28. The'block 35'is pr vided at its under side within-lug 38 located nextadjacent the bar 28a'ndthe under side 4of theblock constitutes ashoulder39 which i a. pawl comprising a 4100 rear side of the bar il iguane yplained. When theblock 35 is the ositon shown in'full lines in -F` 3 othe drawings this llug 38 is locate y above the w` lVhen it'is desiredto renderthe pawlbar inactive, the bar is swung forwardly to the dottedVline position shown in the said Fig.

3 and the lever 37 is rocked so as to lower the block 35.` In thismovement of the block i 4its lug 38 will be brought into positionbetween the rear side of the bar 28 and the upper end of the' oke "30with the shoulder 39 resting upon t e` said upper end of lthe yoke andlimiting the downward movement of the block. By reason of the en gementof the lug 38 between the bar and t e u per end of the yoke, the bar 28will be he d in inactive position or, in otherwords, in positionwithfits pawl 31 outof engagement and out of the path y, of movement ofthe ratchet teeth 34 upon the winding drum.
